The current thinking is that the universe is infinite in spatial extent, 
but only 13.7 billion years old. In consequence of its finite age, we 
can only see a finite amount of it.

So whether it's really infinite in extent is not something we actually 
know, and can probably never know. We also don't know whether the 
physical laws are really the same everywhere. There could be variations 
that are too small to be detectable in the amount of the universe that 
we can see.

In some ways, having physical laws that vary over the universe is 
philosophically attractive, because it could be an answer to why the 
laws we see seem so finely tuned to support our existence.
